Boat Trailer Bolts

Below you will find nearly any size bolt you could possibly need for your boat or utility trailer. These trailer bolts are available in Stainless Steel or Zinc plated, ranging from 1/4 inch, 3/8 inch, and 1/2 inch diameter in many lengths. We stock these bolts specifically for certain trailer applications. Stainless Steel would be the ideal choice for use in saltwater, while zinc plated would be the ideal choice for use in Freshwater. However, both bolt materials are perfectly sufficient for either application.

3/8" Diameter Bolt - Typically used on trailer fenders, brackets, bunk brackets, Disc Brakes, winches, and license plate brackets

7/16" Diameter Bolt - typically used to mount 3,500lb 5 Lug Disc Brake Kit Caliper Brackets to 4 Hole Brake Flange

1/2" Diameter Bolt - Typically used on Tongue Couplers, Fender Bracket Mounts, Leaf Spring Mounting Bolts, and Bunk Board through Bolts 

9/16" Diameter bolt - Used for Trailers with 26" Reverse Curve Leaf Springs
